    Actually it still does the right thing - it fetches all objects, but
    reads only ids of objects from the ResultSet beyond page 1.

    BTW, this is optimized further in 3.0 to read just ids (and do not
    resolve page 1 immediately), but 2.0.x implementation also provides a
    significant performance gain compared to non-paginated queries.
